Drawings of GWR Whistles, relief valves etc.

[deegee]

Hello all,

First ever post… I am trying to build a 5” gauge GWR Grange locomotive and I am hunting for good (accurate to prototype) drawings, in any scale, of the following parts:

> Cylinder relief valves
> Whistles and shield
> Safety Valve / Top feed
> Injectors / Ejectors
> Boiler cleading and smokebox detailing

Any help appreciated.

David.

I built King/Manor & dukedog ,I may be able to help ,I have to look at plans and see what I can email to you .I will try my best please send me your email in a PM .

Maybe this image might help with the whistles.Sorry it's a bit blurred.
There is a good drawing of the safety valve bonnet/top feed covers in Jim Russell's book 'A Pictorial Record of Great Western Engines' at the end of Vol 2.
The National Railway Museum Copy Drawings service have the G.A. and cross sectional drawings,these drawings featured in the Great Western Railway Journal No.s 27 and 28 (Summer and Autumn 1998).
As for the injectors,Doug Hewson sells some accurate injector body castings for the B.R.Standard range of locos,these being derived from the GWR's design.
Also,Polly Model Engineering/Practical Scale/Neville Evans provide drawings and castings for their 5" gauge Penrose Grange loco.
Hope this is of help.

Thanks, the whistles picture is fantastic. I have tried to take pictures of the whistles, safety valves etc. on the hall and manor at didcot have but they are not useful pics really when you are standing on the ground looking up.

I have the Neville Evans drawings but these don't cover these parts really.

I also have all the NRM grange drawings if i have read the catalogue correctly - the cross section and GA are ok but don't give much away. As far as i can tell the NRM only have the following drawings of the grange:

a) good bogie arrangement drawing (common across halls & manors)
b) various grange GAs
c) various drawings of the S/1 boiler including backhead fittings
d) grange frame plan - fiendishly overlayed drawings but very good
e) cross section of the manor

In terms of the injector, how close would the doug hewson BR castings be to the ones used on the grange? I have these castings and they look pretty close to the grange ones from the pictures i have - but it is hard to tell. I wonder if the castle ones are the same as the grange as Pete Rich did some great castle drawings.

I shall track down the jim russel book.

Thanks again for these tips!

David.

David I received your PM and will look for the plans tomorrow and will email you whatever I can from the King plans , they would be the closest .

I may have drawings of some of those fittings on original swindon works drawings, I will have a look for you later, Cheers, Mike

Hi David
I sent you some information , I hope will be of help.

Pleased that the GWR whistle image was of interest.
I think the injector bodies that Doug Hewson sells,look as though they cover most GWR locos,certainly the tank locos.Looking at J.H.Russell's book again,it looks like a few tender loco classes carried these injectors behind the cab steps,though it's difficult to make out what was fitted to the 'Grange' class.
Some years ago a member of the Kinver and West Midlands SME (called Mike Harrison I believe) built a 5" gauge 'Grange' from works drawings.It might be worth contacting him.Here is an image of Mike's loco.
There is also the Betton Grange website.

If you have old drawings that need to be accurately scaled why not convert to CAD. Let me know by PM, I might be able to help.
Cheers

Hi Davd,

If you can get hold of a copy of F.J.Roaches "Historic locomotive drawings in 4mm scale" there are some useful little drawings of fittings that give major dimensions. I've used these as a guide for detailing loco's, if you go wrong you're only a couple of thou out! The main thing is, they look right. I could try and scan the pages for you and mail them to you. Let me know.

Regards,

Waggy.

Got here from google, just wondered if anyone has any plans for a GWR king.
I have a book called GWR Engines - Names, Numbers, Types and Classes but it only gives the major dimensions of the loco.

Thanks.

From memory going back to the early 1980's the GWR injectors differed from BR in internal dimensions only.

Hi David.
I am just finishing a 5"Grange (boiler & steam tests done) and found the Polly Engineering (Neville Evans) drawings for the "Penrhos Grange" a great help, they seem to cover the items you are looking for.

For authoritative info on whistles and gear, what better than GWR Swindon Drg. No. 91470 giving the 1930's Standard Whistles and Gear. This is what we used for sorting out the details on the Collett Goods.

Further to previous, although I have not been able to track down the works drawing for cylinder relief valves, I hope it not out of order to mention that these are available in both 7 1/4 gauge and 5" gauge from Polly.

Hello All.

I've been following the thread and one or two things have come to mind which, although not directly referring to the "Manor's" should be borne in mind when relating to Great Western locomotives if we want to be authentically correct. Prior to 1903 the whistles were different to those we knew. As in later days the normal day whistle was smaller than the danger whistle, and were of a higher pitch and more shrill sounding. Unlike the photo's shown the top securing nut was extended up into a small globe shape. The whistles were always fitted side by side some times on top of the cab roof (Dean Engines ) and in front of the cab on top of the firebox later. Until about 1925 the danger whistle (Large) was always fitted to the right but moved to the left from that date. Some years ago my old friend ob Gale, a steam driver at Severn Tunnel introduced me to the art of blowing "crow's" on the whistle. This was where the engineman would regulate the steam to the whistle whereby he could start the whistle on blow note and expand it through to normal and then fade back. I understand that this practice was often used to signal certain intentions and which routes trains were required to travel on. Hope this helps, Its all food for thought, isn't it.
The Manors were to the "right"

Hello all,
Oops I got in wrong and its vice versa. Prior to 1925 the large whistle was to the left but moved to the right from about that date.
Thereforte on the Manor's it was always large to the right. ( At least I got that part right ).
Taff, in shame.

Hello Taff. I've sent you a PM. No need to reply, just reviving a few dusty memories of Newport!

Gday,
In regards to GWR injects, see the top of page 14 in doug hewson's catalogue. Not sure if these are what you are after or not.

Cheers,
Alex

Can anyone list the specific uses for large and small whistles ie what is considered Normal (Use Small Whistle) and what is Danger (Use Large Whistle)? I have previously been told that one (I believe the small whistle) was for signaling to the guard and the other for everything else.
